Hi
Take a look to this code I found surfing, it creates an image from url then resize it and return it as byte array that you can use to set a blob in the database:
public static byte [] resizeImage(URL url,int widthConstraint,int heightConstraint) throws ImageFormatException, IOException
     ImageIcon imageIcon = new ImageIcon(url);
     Image img = imageIcon.getImage();
     int imgWidth = imageIcon.getIconWidth();
     int imgHeight = imageIcon.getIconHeight();
     ImageIcon adjustedImg=null;
     if ( imgWidth>0 && imgHeight>0)//imgWidth > widthConstraint | imgHeight >  heightConstraint )
     if ( imgWidth > imgHeight )
       // Create a resizing ratio.
       double ratio = (double) imgWidth / (double)
        widthConstraint;
       int newHeight = (int) ( (double) imgHeight / ratio );
       // use Image.getScaledInstance( w, h,
       // constant), where constant is a constant
       // pulled from the Image class indicating how
       // process the image; smooth image, fast
       // processing, etc.
       adjustedImg = new ImageIcon(
        imageIcon.getImage().getScaledInstance(
          widthConstraint, newHeight,
          Image.SCALE_SMOOTH )
     else
       // Create a resizing ratio.
       double ratio = (double) imgHeight / (double)
        heightConstraint;
       int newWidth = (int) ( (double) imgWidth / ratio );
       adjustedImg = new ImageIcon(
       imageIcon.getImage().getScaledInstance( newWidth,
          heightConstraint, Image.SCALE_SMOOTH )
     int resizeWidth = adjustedImg.getIconWidth();
     int resizeHeight = adjustedImg.getIconHeight();
     Panel p = new Panel();
     BufferedImage bi = new BufferedImage(resizeWidth, resizeHeight,
     BufferedImage.TYPE_INT_RGB);
     Graphics2D big = bi.createGraphics();
     big.drawImage(adjustedImg.getImage(), 0, 0, p);
     ByteArrayOutputStream os = new ByteArrayOutputStream();
     JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(os);
     encoder.encode(bi);
     byte[] byteArray = os.toByteArray();
     return byteArray;
  else
  return new byte[0];
   }hope this helps.
